well, I need some advice!! Soon, I'll be getting a 15 gallon tall aquarium for the hermies, and I want to build them a sturdy 2nd level (mainly bc one is getting picked on by 2 others, so he needs his own space). I dont want to buy a suction cup shower thing, bc I have a good-sized crab with a heavy shell - what are my options? I have screwdrivers, nails, a hammer, hot glue, and a hardware store down the road. (the 15G tall has the same base dimensions as a 10G, but its a few inches taller). Also, I'd like the level to be removable, for deep cleans. :hail: Advice would be most welcome!!
